Can't print the skirt properly

[osterac]

So I'm not sure what it was that I did but the printer now only needs some adjustments to steps per mm, but I'm having trouble figuring that out. The ender 4 source code is posted here and I tried using the Arduino IDE to edit the configuration.h file and insert the new steps per mm values, but when I try to upload to the printer, it says "too many decimal points in number." If I try to get the board info from my printer it says this:
BN: Unknown board
VID: 0403
PID: 6001
SN: Upload any sketch to obtain it
The options to adjust steps per mm from within the printer's UI are disabled. Any thoughts on what to do?
Thanks so much
*EDIT*
it was a typo.
Now it says
"Error compiling for board Arduino Mega ADK."
*EDIT2*
Here's the full log

Well that problem is solved. I think I just had the wrong programmer selected - parallel programmer works. I was even able to unlock some cool menu options in ultralcd.h, including the ability to set your steps per mm from the printer menu itself. Just a matter of deleting the comment (//) commands.
Anyway, right now I have an issue with gaps between lines that I was hoping to get some help with. I've tried compensating by adjusting initial layer width and flow, but I get inconsistencies with the width of my print from one layer to the next, and on one circular print I'm getting a large blob on the outer wall. here's what it does with the first layer:

It's not immediately evident here, but it seems to do a better job with one half than the other half. In some prints, half is perfectly connected and the other half is falling apart.
Anyone know what could be causing this?
Thanks
